For people using public transport, Bronx zoo is easily accessed using the 2 and 5 subway lines from Manhattan. There are several entrances to the zoo and each has a subway station nearby. We went in winter, definitely a bad time to visit the zoo. Most animals were not in their exhibits. Even the seabird aviary was closed so we couldn't see the penguin feeding. Other than that I feel it's a great place to spend a day. The sea lion feeding session is definitely awesome. My personal favorites were the the aquatic birds section and the mouse house.
